Description
BACKGROUND
1. Technical Field
The present invention relates to a timepiece for displaying
calendar information.
2. Related Art
In the past, there has been known a timepiece for displaying the
date with an index in analog timepieces (see, e.g., Japanese Patent
No. 2,852,769 (Document 1)).
In the timepiece of Document 1, characters of 1 through 31 are
displayed on an outer peripheral surface of the dial plate, and a
date hand indicates these characters to thereby display the
date.
Incidentally, in timepieces, it is required to display the month
and the number of years elapsed from a leap year (hereinafter
referred to simply as elapsed years) in addition to the date in
some cases as in the perpetual clock. However, in the timepiece of
Document 1, display of the month and the elapsed years is not
disclosed. In the timepiece of Document 1, in order to display the
month and the elapsed years in addition to the date, it is possible
to, for example, make the date hand indicate symbols or a scale
representing January through December and 0 year through 3 years in
addition to the symbols or the scale representing 1.sup.st through
31.sup.st. However, in this case, the number of the symbols and the
scales to be indicated by the date hand increases, and it is
necessary to decrease the distances between the indication
positions. Therefore, there is a problem that it becomes difficult
for the user to check the date, the month, and the elapsed
years.
Further, in the case of the timepiece driven by a rechargeable
battery (a second cell), it is required to detect and then display
the amount of charge of the rechargeable battery in some cases.
However, in the timepiece of Document 1, there is no disclosure
regarding the fact that the battery is the rechargeable type, and
the fact that the amount of charge is displayed. Therefore, there
is desired a timepiece capable of displaying the amount of charge
in addition to the calendar information.
Further, in the case of a timepiece provided with additional
functions such as an alarm function or a chronograph function in
addition to the calendar display function, it is required to
display the information related to the additional functions in some
cases. However, in the timepiece of Document 1, there is no
disclosure regarding the fact that the information related to
additional functions other than the calendar display function is
displayed. Therefore, there is desired a timepiece capable of
displaying the information related to additional functions in
addition to the calendar information.
SUMMARY
An advantage of the invention is to provide a timepiece solving at
least a part of the problems described above.
A first aspect of the invention is related to a timepiece capable
of displaying a plurality of types of calendar information,
including a first index adapted to indicate the type of the
calendar information, and a second index adapted to indicate a
value of the calendar information of the type indicated by the
first index.
The types of the calendar information which can be displayed are,
for example, the day, the month, and the number of years elapsed
from a leap year, and the values of the calendar information are,
for example, numbers of 0 through 31.
According to this aspect of the invention, when, for example, the
user operates a button and so on of the timepiece to make the first
index indicate one of the types of the calendar information, the
second index indicates the value of the calendar information of the
type indicated by the first index. Thus, it is possible for the
user to check the calendar information based on the type of the
calendar information indicated by the first index and the value of
the calendar information indicated by the second index. Further, it
is possible for the user to check a plurality of types of calendar
information by operating the button and so on to switch the type of
the calendar information indicated by the first index.
Further, since it is sufficient for the second index to indicate
the values (0 through 31) of the calendar information, the
intervals of the indication positions of the second index can be
increased, and the calendar information can be displayed in an
easy-to-understand manner compared to the case in which, for
example, the second index indicates symbols or a scale representing
the 1.sup.st through 31.sup.st days, symbols or a scale
representing January through December, and symbols or a scale
representing 0 through 3 years to thereby indicating the calendar
information (1.sup.st through 31.sup.st days, January through
December, and 0 year through 3 years) only with the second
index.
In the timepiece according to the first aspect of the invention, it
is preferable that the types of the calendar information which can
be indicated by the first index are day, month, and a number of
years elapsed from a leap year, and the values of the calendar
information which can be indicated by the second index are numbers
of 0 through 31.
According to the aspect of the invention with this configuration,
out of the numbers 0 through 31, the second index indicates either
of the numbers 1 through 31 in the case in which the first index
indicates the day, indicates either of the numbers 1 through 12 in
the case in which the first index indicates the month, or indicates
either of the numbers 0 through 3 in the case in which the first
index indicates the elapsed years. Therefore, it is possible for
the second index to indicate the value of the plurality of types of
calendar information representing the values of the day, the month,
and the elapsed years by indicating the 32 values of 0 through
31.
In the timepiece according to the first aspect of the invention, it
is preferable that the first index is configured so as to be able
to indicate a day of the week, and in a case in which the first
index indicates the day of the week, the second index indicates the
value of the day.
According to the aspect of the invention with this configuration,
it is possible for the user to check the day of the week, and at
the same time check the fact that the type of the calendar
information is the day by the first index indicating the day of the
week, and to check the value of the day based on the value
indicated by the second index.
In general, the user may have an idea of checking the day of the
week together with the value of the day in some cases. Therefore,
by making it possible for the user to check the day of the week
together with the value of the day, it is possible to make the
timepiece easier to use.
Further, according to the aspect of the invention with this
configuration, since there is no need to separately provide a
dedicated index to the indication of the day of the week in
addition to the first index and the second index, the number of the
indexes provided to the timepiece can be decreased compared to the
case of separately providing the dedicated index.
In the timepiece according to the first aspect of the invention, it
is preferable that the types of the calendar information which can
be indicated by the first index are day, month, and a number of
years elapsed from a leap year, the values of the calendar
information which can be indicated by the second index are numbers
of 0 through 31, the second index is configured so as to be able to
make a movement with a normal rotation and a movement with a
reverse rotation, and a movement range of the second index is
limited within a range of indicating the numbers of 1 through 12 in
a case in which the first index indicates the month, and limited
within a range of indicating the numbers of 0 through 3 in a case
in which the first index indicates the number of years elapsed from
a leap year.
Here, the indication positions of the numbers of 0 through 31 with
the second index are arranged so that the numbers of 0 through 31
are indicated in series in the case in which the second index makes
a movement with the normal rotation.
According to the aspect of the invention with this configuration,
in the case in which the time has passed and the value of the
calendar information has been updated, and the second index
indicates the next value, and the case of making the second index
indicate the next value when the user operates the crown or the
like of the timepiece to move the second index to thereby set the
value of the calendar information, the second index moves in the
following manner.
Specifically, in the case in which the first index indicates the
month, and the second index indicates the number of 12, the second
index makes a movement with the reverse rotation to indicate the
number of 1 passing through the positions of indicating the numbers
of 2 through 11. Therefore, the movement length of the second index
can be shortened compared to the case in which the second index
makes a movement with the normal rotation to indicate the number of
1 passing through the positions of indicating the numbers of 13
through 31 and 0.
Further, in the case in which the first index indicates the elapsed
years, and the second index indicates the number of 3, the second
index makes a movement with the reverse rotation to indicate the
number of 0 passing through the positions of indicating the numbers
of 1 and 2. Therefore, the movement length of the second index can
be shortened compared to the case in which the second index makes a
movement with the normal rotation to indicate the number of 0
passing through the positions of indicating the numbers of 4
through 31.
Thus, the power consumption of the timepiece can be reduced, and
further, the setting of the values of the calendar information can
promptly be performed.
It should be noted that in the case in which the first index
indicates the day, and the second index indicates the number of 31,
the second index makes a movement with the normal rotation to
indicate the number of 1 passing through the position of indicating
the numbers of 0.
In the timepiece according to the first aspect of the invention, it
is preferable that the types of the calendar information which can
be indicated by the first index are day, month, and a number of
years elapsed from a leap year, the values of the calendar
information which can be indicated by the second index are numbers
of 0 through 31, and the second index moves through a position of
indicating the number of 0 with fast-forwarding in a case in which
the first index indicates the day, through positions of indicating
the numbers of 0 and 13 through 31 with fast-forwarding in a case
in which the first index indicates the month, and through positions
of indicating the numbers of 4 through 31 with fast-forwarding in a
case in which the first index indicates the number of years elapsed
from a leap year.
According to the aspect of the invention with this configuration,
when the user sets the values of the calendar information by
operating the crown and so on of the timepiece to move the second
index, since the second index moves through the positions of
indicating the values, which are not the setting target, with
fast-forwarding, setting of the values of the calendar information
can promptly be performed compared to the case in which the
fast-forwarding is not used in the movement.
In the timepiece according to the first aspect of the invention, it
is preferable to further include a first drive unit adapted to
drive the first index, a second drive unit adapted to drive the
second index, an operation unit, a detection section adapted to
detect an operation to the operation unit to output a detection
signal upon detection of the operation, and a calendar display
processing section adapted to control the first drive unit to
switch the type of the calendar information indicated by the first
index upon input of the detection signal, and control the second
drive unit to make the second index indicate the value of the
calendar information of the type indicated by the first index upon
input of the detection signal.
According to the aspect of the invention with this configuration,
by the user operating the operation unit, the detection signal is
output from the detection section, and then the detection signal is
input to the calendar display processing section. Then, the
calendar display processing section switches the types of the
calendar information to be indicated by the first index, and makes
the second index indicate the value of the calendar information of
the type indicated by the first index.
According to this configuration, the user can immediately check the
calendar information of the type the user wants to check by
operating the operation unit.
A second aspect of the invention is related to a timepiece capable
of displaying a plurality of types of calendar information,
including a secondary cell, a charge amount detection section
adapted to detect an amount of charge of the secondary cell, a
first index adapted to indicate the type of the calendar
information, and a second index adapted to indicate a value of the
calendar information of the type indicated by the first index,
wherein the first index is configured so as to be able to indicate
the charge amount.
The types of the calendar information which can be displayed are,
for example, the day, the month, and the number of years elapsed
from a leap year, and the values of the calendar information are,
for example, numbers of 0 through 31.
According to this aspect of the invention, when, for example, the
user operates a button and so on of the timepiece to make the first
index indicate one of the types of the calendar information, the
second index indicates the value of the calendar information of the
type indicated by the first index. Thus, it is possible for the
user to check the calendar information based on the type of the
calendar information indicated by the first index and the value of
the calendar information indicated by the second index. Further, it
is possible for the user to check a plurality of types of calendar
information by operating the button and so on to switch the type of
the calendar information indicated by the first index.
Further, since it is sufficient for the second index to indicate
the values (0 through 31) of the calendar information, the
intervals of the indication positions of the second index can be
increased, and the calendar information can be displayed in an
easy-to-understand manner compared to the case in which, for
example, the second index indicates symbols or a scale representing
the 1.sup.st through 31.sup.st days, symbols or a scale
representing January through December, and symbols or a scale
representing 0 through 3 years to thereby indicating the calendar
information (1.sup.st through 31.sup.st days, January through
December, and 0 year through 3 years) only with the second
index.
Further, according to this aspect of the invention, it is possible
for the user to check the charge amount by operating the button or
the like of the timepiece to make the first index indicate the
charge amount.
Further, in this aspect of the invention, since the indication of
the charge amount is performed by the first index for indicating
the type of the calendar information, there is no need to
separately provide a dedicated index to the indication of the
charge amount, and the number of the indexes provided to the
timepiece can be decreased compared to the case of separately
providing the dedicated index.
Further, according to this aspect of the invention, it is also
possible to make, for example, the second index indicate the value
of the specific type of the calendar information when the first
index indicates the charge amount. In this case, the user can check
the charge amount and the calendar information at the same
time.
In the timepiece according to the second aspect of the invention,
it is preferable that the types of the calendar information which
can be indicated by the first index are day, month, and a number of
years elapsed from a leap year, and the values of the calendar
information which can be indicated by the second index are numbers
of 0 through 31.
According to the aspect of the invention with this configuration,
out of the numbers 0 through 31, the second index indicates either
of the numbers 1 through 31 in the case in which the first index
indicates the day, indicates either of the numbers 1 through 12 in
the case in which the first index indicates the month, or indicates
either of the numbers 0 through 3 in the case in which the first
index indicates the elapsed years. Therefore, it is possible for
the second index to indicate the value of the plurality of types of
calendar information representing the values of the day, the month,
and the elapsed years by indicating the 32 values of 0 through
31.
In the timepiece according to the second aspect of the invention,
it is preferable that in a case in which the first index indicates
the charge amount, the second index indicates the value of the
day.
According to the aspect of the invention with this configuration,
it is possible for the user to check the charge amount, and at the
same time check the fact that the type of the calendar information
is the day by the first index indicating the charge amount, and to
check the value of the day based on the value indicated by the
second index.
Therefore, since the user can always check the value of the day and
the charge amount by keeping the first index indicating the charge
amount, it is possible to make the timepiece easier to use.
In the timepiece according to the second aspect of the invention,
it is preferable that the first index is configured so as to be
able to indicate a day of the week, and in a case in which the
first index indicates the day of the week, the second index
indicates the value of the day.
According to the aspect of the invention with this configuration,
it is possible for the user to check the day of the week, and at
the same time check the fact that the type of the calendar
information is the day by the first index indicating the day of the
week, and to check the day information based on the value indicated
by the second index.
In general, the user may have an idea of checking the day of the
week together with the value of the day in some cases. Therefore,
by making it possible for the user to check the day of the week
together with the value of the day, it is possible to make the
timepiece easier to use.
Further, according to the aspect of the invention with this
configuration, since there is no need to separately provide a
dedicated index to the indication of the day of the week in
addition to the first index and the second index, the number of the
indexes provided to the timepiece can be decreased compared to the
case of separately providing the dedicated index.
In the timepiece according to the second aspect of the invention,
it is preferable that in a case in which indication of the charge
amount by the first index is absent, the first index indicates the
charge amount in accordance with a drop of the charge amount to a
level lower than a predetermined threshold value.
According to the aspect of the invention with this configuration,
even in the case in which the first index does not indicate the
charge amount, if the charge amount of the secondary cell drops to
a level lower than the threshold value, the first index
automatically indicates the charge amount, and therefore, the user
can check the fact that the charge amount has dropped. Thus, it is
possible to surely inform the user of the fact that the charge
amount of the secondary cell has dropped to thereby reduce the
possibility that the charge fails to occur to cause a system
failure.
In the timepiece according to the second aspect of the invention,
it is preferable that the timepiece is capable of performing a
function other than the function of displaying the calendar
information, the first index is configured so as to be able to
indicate a type of the additional function, and there is further
included a third index adapted to indicate information related to
the function of the type indicated by the first index in a case in
which the first index indicates the type of the additional
function.
The additional function is, for example, an alarm function, and the
information related to the additional function is, for example,
alarm time.
According to the aspect of the invention with this configuration,
by checking the type of the function indicated by the first index,
the user can check what function is related to the information
indicated by the third index.
Further, according to the aspect of the invention with this
configuration, it is also possible to make, for example, the second
index indicate the value of the specific type of the calendar
information when the first index indicates the type of the
additional function. In this case, the user can check the
information related to the additional function and the calendar
information at the same time.
In the timepiece according to the second aspect of the invention,
it is preferable that execution of the additional function is
restricted in a case in which the charge amount reaches a level
lower than a predetermined threshold value.
According to the aspect of the invention with this configuration,
since the execution of the additional function is restricted if the
charge amount drops to a level lower than the threshold value, the
power consumption can be reduced compared to the case in which the
restriction is not applied, and the possibility of the system
failure can be reduced. Further, the situation that the additional
function is not correctly performed can be prevented from
occurring.
In the timepiece according to the second aspect of the invention,
it is preferable to further include a first drive unit adapted to
drive the first index, a second drive unit adapted to drive the
second index, an operation unit, a detection section adapted to

processing section adapted to control the first drive unit to
switch an indication position of the first index upon input of the
detection signal, and control the second drive unit to make the
second index indicate the value of the calendar information of the
type indicated by the first index in a case in which the first
index indicates the type of the calendar information.
According to the aspect of the invention with this configuration,
by the user operating the operation unit, the detection signal is
output from the detection section, and then the detection signal is
input to the calendar display processing section. Then, the
calendar display processing section switches the indication
position of the first index, and makes the second index indicate
the value of the calendar information of the type indicated by the
first index in the case in which the first index indicates the type
of calendar information.
According to this configuration, the user can immediately check the
calendar information of the type the user wants to check and the

calendar information indicated by the first index and the value of
the calendar information indicated by the second index. Further, it
is possible for the user to check a plurality of types of calendar
information by operating the button and so on to switch the type of
the calendar information indicated by the first index.
Further, since it is sufficient for the second index to indicate
the values (0 through 31) of the calendar information, the
intervals of the indication positions of the second index can be
increased, and the calendar information can be displayed in an
easy-to-understand manner compared to the case in which, for
example, the second index indicates symbols or a scale representing
the 1.sup.st through 31.sup.st days, symbols or a scale
representing January through December, and symbols or a scale
representing 0 through 3 years to thereby indicating the calendar
information (1.sup.st through 31.sup.st days, January through
December, and 0 year through 3 years) only with the second
index.
Further, according to this aspect of the invention, when the user
operates a button and so on of the timepiece to make the first
index indicate the type of the additional function, the third index
indicates the information related to the function of the type
indicated by the first index. Therefore, by checking the type of
the function indicated by the first index, the user can check what
function is related to the information indicated by the third
index.
Further, according to this aspect of the invention, it is also
possible to make, for example, the second index indicate the value

information related to the function of the type indicated by the
first index with the third index, the number of the indexes
provided to the timepiece can be reduced compared to the case of
separately providing the dedicated indexes to the respective
functions. Further, since the indication area of the indexes can be
enlarged, the information related to each of the functions can be
displayed in an easy-to-understand manner.
In the timepiece according to the third aspect of the invention, it
is preferable that the types of the calendar information which can
be indicated by the first index are day, month, and a number of
years elapsed from a leap year, and the values of the calendar
information which can be indicated by the second index are numbers
of 0 through 31.
According to the aspect of the invention with this configuration,
out of the numbers 0 through 31, the second index indicates either
of the numbers 1 through 31 in the case in which the first index
indicates the day, indicates either of the numbers 1 through 12 in
the case in which the first index indicates the month, or indicates
either of the numbers 0 through 3 in the case in which the first
index indicates the elapsed years. Therefore, it is possible for
the second index to indicate the value of the plurality of types of
calendar information representing the values of the day, the month,
and the elapsed years by indicating the 32 values of 0 through
31.
In the timepiece according to the third aspect of the invention, it
is preferable that the first index is configured so as to be able
to indicate a day of the week, and in a case in which the first
index indicates the day of the week, the second index indicates the

it is possible for the user to check the day of the week, and at
the same time check the fact that the type of the calendar
information is the day by the first index indicating the day of the
week, and to check the day information based on the value indicated
by the second index.
In general, the user may have an idea of checking the day of the
week together with the value of the day in some cases. Therefore,
by making it possible for the user to check the day of the week
together with the value of the day, it is possible to make the
timepiece easier to use.
Further, according to the aspect of the invention with this
configuration, since there is no need to separately provide a
dedicated index to the indication of the day of the week, the
number of the indexes provided to the timepiece can be decreased

small window 30.
Further, the analog electronic watch 1 is provided with the second
index 13 as a center hand having a rotary shaft located at the
center of the dial plate 2. Further, on the outer peripheral
surface of the dial plate 2, there are displayed numbers of 0
through 31 along the outer peripheral edge. Here, the numbers of 0
through 31 are arranged clockwise in series from the 12 o'clock
position viewed from the obverse side of the clock. It should be
noted that although the numbers of 1 through 31 are arranged at
regular intervals, the distance between 0 and 1, and the distance
between 31 and 0 are larger than the distances between other
numbers. By the second index 13 indicating these numbers, there is
indicated the value of the calendar information of either of the
types of the day, the month, and the elapse years from a leap year
(0, +1 through +3).
Further, the analog electronic watch 1 is provided with a first
index 21 disposed in the first small window 20. Further, in the
periphery of the first small window 20, characters of "S," "M,"
"T," "W," "T," "F," "S" respectively representing seven days of the
week of Sunday through Saturday are displayed in the vicinity of
the 1 o'clock position through the vicinity of the 4 o'clock
position of the first small window 20. Further, in the periphery of
the first small window 20, a character of "M" representing the
month is displayed in the vicinity of the 8 o'clock position of the
first small window 20, and a character of "L" representing the
elapsed years is displayed in the vicinity of the 10 o'clock
position.
The first index 21 indicates one of the characters "S" through "S"
representing the seven days of the week to thereby indicate the day
of the week. Further, the first index 21 indicates the type of the
calendar information. In other words, by indicating the characters
"S" through "S," the first index 21 indicates the day of the week,
and at the same time indicates the fact that the type of the
calendar information is the day. Further, the first index 21
indicates the character "M" to thereby indicate the fact that the
type of the calendar information is the month. Further, the first
index 21 indicates the character "L" to thereby indicate the fact
that the type of the calendar information is the elapsed years.
Further, the analog electronic watch 1 is provided with a crown 3
as an external operation member, and a button 4, which is also an
external operation member. Here, the button 4 constitutes an
operation unit according to the invention.
FIG. 2 is a block diagram showing a configuration of the analog

As shown in FIG. 2, the indexes 11 through 13, 21, and 31 are
respectively driven by four step motors. Specifically, the second
hand 31 is driven by the step motor 41 for the second hand, the
hour hand 11 and the minute hand 12 are driven by the step motor 42
for the hour hand and the minute hand, the first index 21 is driven
by the step motor 43 for the first index, and the second index 13
is driven by the step motor 44 for the second index. Here, the step
motor. 43 for the first index constitutes a first drive unit
according to the invention, and the step motor 44 for the second
index constitutes a second drive unit according to the invention.
It should be noted that it is also possible for the second hand 31,
the hour hand 11, and the minute hand 12 to be driven by a common
step motor.
In order to perform the drive control of each of the step motors 41
through 44, a drive control circuit 50 is incorporated in the
analog electronic watch 1.
The drive control circuit 50 is provided with a first switch
detection section 51, a second switch detection section 52, a
function processing section 53, a time hand drive control section
54, a first index drive control section 55, a second index drive
control section 56, and a calendar information storage section
57.
The first switch detection section 51 detects a push-in operation
of the button 4, and outputs the detection signal to the function
processing section 53 in the case in which the push-in operation
has occurred. Here, the first switch detection section 51
constitutes a detection section according to the invention.
The second switch detection section 52 detects an operation of the
crown 3, and outputs a detection signal corresponding to the
operation to the function processing section 53 in the case in
which the operation has occurred.
The time hand drive control section 54 outputs a motor drive pulse
using a reference signal (e.g., a signal of 1 Hz) output from a
reference signal generation circuit such as a crystal resonator to
control the step motor 41 for the second hand and the step motor 42
for the hour hand and the minute hand to thereby control the drive
of the hour hand 11, the minute hand 12, and the second hand
31.
The first index drive control section 55 outputs a motor drive
pulse using the reference signal output from the reference signal
generation circuit to control the step motor 43 for the first index
to thereby control the drive of the first index 21.
The second index drive control section 56 outputs a motor drive
pulse using the reference signal output from the reference signal
generation circuit to control the step motor 44 for the second
index to thereby control the drive of the second index 13.
The calendar information storage section 57 stores day information
representing the value of the day, month information representing
the value of the month, elapsed-year information representing the
value of the elapsed years, and day-of-the-week information
representing the day of the week. The calendar information stored
in the calendar information storage section 57 is set by a calendar
information setting section 533 described later, and is updated by
a calendar information update section 534 described later.
The function processing section 53 is for performing processing of
a variety of functions in the analog electronic watch 1. The
function processing section 53 is provided with a time display
processing section 531, a calendar display processing section 532,
a calendar information setting section 533, and a calendar
information update section 534.
The time display processing section 531 is for displaying the hour,
the minute, and the second of the current time with the hour hand
11, the minute hand 12, and the second hand 31 using the time hand
drive control section 54.
The calendar information setting section 533 sets the values of the
calendar information stored in the calendar information storage
section 57 based on the operation of the button 4 in a calendar
information setting mode. It should be noted that the specific
setting process of the calendar information will be described
later.
The calendar information update section 534 measures the time using
the reference signal output from the reference signal generation
circuit, and then updates the values of the calendar information
stored in the calendar information storage section 57 in accordance
with the passage of time. Therefore, the calendar information
storage section 57 stores the current day information, the current
month information, the current elapsed-year information, and the
current day-of-the-week information.
The calendar display processing section 532 is provided with a
first processing section 532A and a second processing section
532B.
The first processing section 532A controls the step motor 43 for
the first index to thereby control the movement of the first index
21. Specifically, when the button 4 is pushed in, and the detection
signal is input from the first switch detection section 51 in a
normal mode, the first processing section 532A moves the first
index 21 to switch the type of the calendar information indicated
by the first index 21.
Here, when making the first index 21 indicate the fact that the
type of the calendar information is the day, the first processing
section 532A makes the first index 21 indicate the character
corresponding to the day-of-the-week information stored in the
calendar information storage section 57 out of the characters "S"
through "S" representing the seven days of the week to thereby
indicate the day of the week.
The second processing section 532B controls the step motor 44 for
the second index to thereby control the movement of the second
index 13.
Specifically, when the type of the calendar information to be
indicated by the first index 21 has been switched in the normal
mode, the second processing section 532B makes the second index 13
indicate the number corresponding to the value of the type of the
calendar information to be indicated by the first index 21 out of
the calendar information stored in the calendar information storage
section 57 to thereby indicate the value of the calendar
information.
Calendar Information Setting Process
Then, the setting process of the calendar information stored in the
calendar information storage section 57 will be described.
When the crown 3 is pulled out, the function processing section 53
makes the transition to the calendar information setting mode. When
the button 4 is held down in this state, the first processing
section 532A moves the first index 21 to sequentially indicate the
characters "S" through "S" representing the seven days of the week,
the character "M" representing the month, and the character "L"
representing the elapsed years. Further, when the crown 3 is
rotationally operated, the second processing section 532B moves the
second index 13.
Then, when the crown 3 is rotationally operated to move the second
index 13 and then the crown 3 is pushed in in the state in which
the first index 21 indicates either of the characters "S" through
"S," the calendar information setting section 533 sets the value of
the number indicated by the second index 13 as the value of the day
information of the calendar information storage section 57.
Further, when the crown 3 is rotationally operated to move the
second index 13 and then the crown 3 is pushed in in the state in
which the first index 21 indicates the character "M" representing
the month, the calendar information setting section 533 sets the
value of the number indicated by the second index 13 as the value
of the month information of the calendar information storage
section 57.
Further, when the crown 3 is rotationally operated to move the
second index 13 and then the crown 3 is pushed in in the state in
which the first index 21 indicates the character "L" representing
the elapsed years, the calendar information setting section 533
sets the value of the number indicated by the second index 13 as
the value of the elapsed-year information of the calendar
information storage section 57.
It should be noted that when the crown 3 is pushed in in the state
in which the first index 21 indicates either of the characters "S"
through "S" representing the seven days of the week, the calendar
information setting section 533 sets the day of the week indicated
by the first index 21 as the day-of-the-week information of the
calendar information storage section 57.
Then, when the crown 3 is pushed in as described above, the
function processing section 53 makes the transition to the normal
mode.
It should be noted that in the present embodiment, although the
second index 13 is moved by the crown 3 being rotationally operated
in the calendar information setting mode, it is also possible to
provide a button different from the button 4 to the analog
electronic watch 1, and arrange that the second index 13 is moved
by the button being pushed in.
Calendar Display Process
Then, the calendar display process performed by the calendar
display processing section 532 will be described.
FIG. 3 is a flowchart showing the calendar display process. The
calendar display process is performed while the function processing
section 53 is in the normal mode.
When the calendar display process is performed, the first
processing section 532A makes the first index 21 move to indicate
the character corresponding to the day-of-the-week information
stored in the calendar information storage section 57 out of the
characters "S" through "S" representing the seven days of the week
to thereby indicate the day of the week as shown in FIG. 1.
Further, thus, the first processing section 532A makes the first
index 21 indicate the fact that the type of the calendar
information is the day. Further, the second processing section 532B
moves the second index 13 to indicate the number corresponding to
the value (1 through 31) of the day information stored in the
calendar information storage section 57 to thereby indicate the
value of the day information. Due to these operations, the day
information is displayed (S11). It should be noted that this
display state corresponds to a display state in the normal
period.
Then, the calendar display processing section 532 determines
whether or not the detection signal is input from the first switch
detection section 51 to thereby determine (S12) whether or not the
button 4 has been held down.
In the case in which the determination of NO has been made in the
step S12, the first processing section 532A and the second
processing section 532B continue the process of the step S11. It
should be noted that in the case in which the time has passed while
the state of YES is not determined in the step S12, and the value
of the day information and the day-of-the-week information stored
in the calendar information storage section 57 have been updated,
the first processing section 532A moves the first index 21 to
indicate the day of the week having been updated, and the second
processing section 532B moves the second index 13 to indicate the
value of the day information having been updated.
On the other hand, in the case in which the determination of YES
has been made in the step S12, the first processing section 532A
moves the first index 21 to indicate the character "M" representing
the month, and thus indicate the fact that the type of the calendar
information is the month as shown in FIG. 4. Further, the second
processing section 532B moves the second index 13 to indicate the
number corresponding to the value (1 through 12) of the month
information stored in the calendar information storage section 57
to thereby indicate the value of the month information. Due to
these operations, the month information is displayed (S13).
Then, the calendar display processing section 532 determines (S14)
whether or not the detection signal has been input from the first
switch detection section 51.
In the case in which the determination of NO has been made in the
step S14, the first processing section 532A and the second
processing section 532B continue the process of the step S13. It
should be noted that in the case in which the time has passed while
the state of YES is not determined in the step S14, and the value
of the month information stored in the calendar information storage
section 57 has been updated, the second processing section 532B
moves the second index 13 to indicate the value of the month
information having been updated.
On the other hand, in the case in which the determination of YES
has been made in the step S14, the first processing section 532A
moves the first index 21 to indicate the character "L" representing
the elapsed years, and thus indicate the fact that the type of the
calendar information is the elapsed years as shown in FIG. 5.
Further, the second processing section 532B moves the second index
13 to indicate the number corresponding to the value (0 through 3)
of the elapsed-year information stored in the calendar information
storage section 57 to thereby indicate the value of the
elapsed-year information. Due to these operations, the elapsed-year
information is displayed (S15).
Then, the calendar display processing section 532 determines (S16)
whether or not the detection signal has been output from the first
switch detection section 51.
In the case in which the determination of NO has been made in the
step S16, the first processing section 532A and the second
processing section 532B continue the process of the step S15. It
should be noted that in the case in which the time has passed while
the state of YES is not determined in the step S16, and the value
of the elapsed-year information stored in the calendar information
storage section 57 has been updated, the second processing section
532B moves the second index 13 to indicate the value of the
elapsed-year information having been updated.
On the other hand, in the case in which the determination of YES
has been made in the step S16, the calendar display processing
section 532 returns the process to the step S11, and then
repeatedly performs the processes of the steps S11 through S16.
Method of Moving Second Index
Then, a method of moving the second index 13 by the second
processing section 532B will be described.
The second processing section 532B moves the second index 13 in the
following manner when the time has passed, the value of the
calendar information stored in the calendar information storage
section 57 has been updated, and the second index 13 is made to
indicate the next value, or when the crown 3 has been rotationally
operated in the calendar information setting mode, and the second
index 13 is made to indicate the next value.
Firstly, there will be described the case in which the first index
21 indicates the day of the week to thereby indicate the fact that
the type of the calendar information is the day. In this case, in
the case in which the second index 13 indicates either of the
numbers of 1 through 30, the second index 13 is rotated clockwise
(normal rotation) viewed from the obverse side of the watch to
indicate the next number. Further, in the case in which the second
index 13 indicates the number of 31, the second index 13 is rotated
clockwise to indicate the number of 1 after passing through the
position of indicating the number of 0 with fast-forwarding as
shown in FIG. 6.
Then, there will be described the case in which the first index 21
indicates the character "M" representing the month to thereby
indicate the fact that the type of the calendar information is the
month. In this case, in the case in which the second index 13
indicates either of the numbers of 1 through 11, the second index
13 is rotated clockwise to indicate the next number. Further, in
the case in which the second index 13 indicates the number of 12,
the second index 13 is rotated counterclockwise (reverse rotation)
to indicate the number of 1 after passing through the positions of
indicating the numbers of 2 through 11 as shown in FIG. 7.
According to this operation, the movement length of the second
index 13 can be shortened compared to the case of rotating the
second index 13 clockwise to indicate the number of 1 after passing
through the positions of indicating the numbers of 13 through 31
and 0. In such a manner, the movement range of the second index 13
is limited to the inside of the range indicating the numbers of 1
through 12.
Then, there will be described the case in which the first index 21
indicates the character "L" representing the elapsed years to
thereby indicate the fact that the type of the calendar information
is the elapsed years. In this case, in the case in which the second
index 13 indicates either of the numbers of 0 through 2, the second
index 13 is rotated clockwise to indicate the next number. Further,
in the case in which the second index 13 indicates the number of 3,
the second index 13 is rotated counterclockwise to indicate the
number of 0 after passing through the positions of indicating the
numbers of 1 and 2 as shown in FIG. 8. According to this operation,
the movement length of the second index 13 can be shortened
compared to the case of rotating the second index 13 clockwise to
indicate the number of 0 after passing through the positions of
indicating the numbers of 4 through 31. In such a manner, the
movement range of the second index 13 is limited to the range
indicating the numbers of 0 through 3.
Functions and Advantages of First Embodiment
When the user operates the button 4 to make the first index 21
indicate one of the types of the calendar information, the second
index 13 indicates the value of the calendar information of the
type indicated by the first index 21. Thus, it is possible for the
user to check the calendar information based on the type of the
calendar information indicated by the first index 21 and the value
of the calendar information indicated by the second index 13.
Further, it is possible for the user to check the day information,
the month information, and the elapsed-year information by
operating the button 4 to switch the type of the calendar
information indicated by the first index 21. In other words, the
user can immediately check the calendar information of the type the
user wants to check by operating the button 4.
Further, since it is sufficient for the second index 13 to indicate
the values (0 through 31) of the calendar information, the
intervals of the indication positions of the second index 13 can be
increased, and the calendar information can be displayed in an
easy-to-understand manner compared to the case in which, for
example, the second index 13 indicates symbols or a scale
representing the 1.sup.st through 31.sup.st days, symbols or a
scale representing January through December, and symbols or a scale
representing 0 through 3 years to thereby indicating the day
information, the month information, and the elapsed-year
information only with the second index 13.
Out of the numbers 0 through 31, the second index 13 indicates
either of the numbers 1 through 31 in the case in which the first
index 21 indicates the day, indicates either of the numbers 1
through 12 in the case in which the first index 21 indicates the
month, or indicates either of the numbers 0 through 3 in the case
in which the first index 21 indicates the elapsed years. Therefore,
it is possible for the second index 13 to indicate the value of the
day information, the value of the month information, and the value
of the elapsed-year information by indicating the 32 values of 0
through 31.
The first index 21 indicates the day of the week to thereby
indicate the fact that the type of the calendar information is the
day. Therefore, it is possible for the user to check the day of the
week, and at the same time check the fact that the type of the
calendar information is the day by the first index 21 indicating
the day of the week, and to check the day information based on the
value indicated by the second index 13. Thus, it is possible to
make the analog electronic watch 1 easier to use. Further, since
there is no need to separately provide a dedicated index to the
indication of the day of the week in addition to the first index 21
and the second index 13, the number of the indexes provided to the
analog electronic watch 1 can be decreased compared to the case of
separately providing the dedicated index. Thus, the number of step
motors and gears can also be reduced.
The movement range of the second index 13 is limited to the range
of indicating the numbers 1 through 12 in the case in which the
first index 21 indicates the month, or is limited to the range of
indicating the numbers 0 through 3 in the case in which the first
index 21 indicates the elapsed years. Therefore, as described
above, the movement length of the second index 13 can be decreased
when the value of the calendar information stored in the calendar
information storage section 57 is updated, and the second index 13
moves, and when the second index 13 moves in the calendar
information setting mode. Thus, the power consumption of the analog
electronic watch 1 can be reduced, and further, the setting of the
values of the calendar information can promptly be performed.
Second Embodiment
FIG. 9 is a front view showing an analog electronic watch A1.
As shown in FIG. 9, the analog electronic watch A1 is provided with
a dial plate A2 having a circular shape. The dial plate A2 is
provided with a first small window A20 having a circular shape and
located at a position shifted toward the 12 o'clock direction from
the center, and the second small window 30 having a circular shape
and located at the position shifted toward the 6 o'clock direction
from the center viewed from the obverse side of the watch.
Further, the analog electronic watch A1 is provided with the hour
hand 11, the minute hand 12, the second hand 31, and the second
index 13 similarly to the analog electronic watch 1 according to
the first embodiment. Further, on the outer peripheral surface of
the dial plate A2, there are displayed the numbers of 0 through 31
similarly to the analog electronic watch 1.
Further, the analog electronic watch A1 is provided with the first
index 21 disposed in the first small window A20. Further, in the
periphery of the first small window A20, there is displayed a
symbol 22 having a crescent sickle-like shape, which is thick in an
end portion (a tip end) in the direction toward the 11 o'clock
position, and is thin in an end portion (a base end) in the
direction toward the 7 o'clock position, from the vicinity of the 7
o'clock position of the first small window A20 through the vicinity
of the 11 o'clock position thereof. The symbol 22 is a power
indicator of a secondary cell 5 (see FIG. 10). Further, in the
periphery of the first small window A20, the character of "M"
representing the month is displayed in the vicinity of the 2
o'clock position of the first small window A20, and the character
of "L" representing the elapsed years is displayed in the vicinity
of the 4 o'clock position.
The first index 21 indicates the position corresponding to an
amount of charge (a remaining battery level) of the secondary cell
5 in the symbol 22 to thereby indicate the amount of the charge.
Further, the first index indicates the type of the calendar
information. Specifically, the first index 21 indicates the symbol
22 to thereby indicate the charge amount, and at the same time
indicate the fact that the type of the calendar information is the
day. Further, the first index 21 indicates the character "M" to
thereby indicate the fact that the type of the calendar information
is the month. Further, the first index 21 indicates the character
"L" to thereby indicate the fact that the type of the calendar
information is the elapsed years.
Further, the analog electronic watch A1 is provided with the crown
3 and the button 4.
FIG. 10 is a block diagram showing a configuration of the analog
electronic watch A1.
As shown in FIG. 10, the indexes 11 through 13, 21, and 31 are
respectively driven by the four step motors 41 through 44 similarly
to the analog electronic watch 1 according to the first
embodiment.
Further, the analog electronic watch A1 is provided with a solar
panel 6 as a power-generator device, and the secondary cell 5 in
which the electric energy generated in the solar panel 6 is
charged. The secondary cell 5 constitutes a power supply of the
analog electronic watch A1.
The analog electronic watch A1 incorporates a drive control circuit
A50.
The drive control circuit A50 is provided with the first switch
detection section 51, the second switch detection section 52, a
function processing section A53, the time hand drive control
section 54, the first index drive control section 55, the second
index drive control section 56, the calendar information storage
section 57, and a charge amount detection section 58.
The charge amount detection section 58 detects the amount of the
charge (the remaining battery level) of the secondary cell 5. The
detection of the charge amount is performed at, for example,
regular time intervals.
The function processing section A53 is provided with a time display
processing section A531, a calendar display processing section
A532, a calendar information setting section A533, and a calendar
information update section A534.
The time display processing section A531, the calendar information
setting section A533, and the calendar information update section
A534 have substantially the same functions as those of the time
display processing section 531, the calendar information setting
section 533, and the calendar information update section 534 of the
analog electronic watch 1 according to the first embodiment.
The calendar display processing section A532 is provided with a
first processing section A532A and a second processing section
A532B.
The first processing section A532A controls the step motor 43 for
the first index to thereby control the movement of the first index
21.
Specifically, when the button 4 is pushed in, and the detection
signal is input from the first switch detection section 51, the
first processing section A532A moves the first index 21 to make the
first index 21 indicate the type of the calendar information and
the charge amount detected by the charge amount detection section
58 in a switching manner.
Here, when the first processing section A532A makes the first index
21 indicate the fact that the type of the calendar information is
the day, the first processing section A532A makes the first index
21 indicate the symbol 22 to indicate the charge amount detected by
the charge amount detection section 58.
The second processing section A532B controls the step motor 44 for
the second index to thereby control the movement of the second
index 13.
Specifically, when the type of the calendar information to be
indicated by the first index 21 has been switched, the second
processing section A532B makes the second index 13 indicate the
number corresponding to the value of the type of the calendar
information to be indicated by the first index 21 out of the
calendar information stored in the calendar information storage
section 57 to thereby indicate the value of the calendar
information.
Calendar Information Setting Process
Then, the setting process of the calendar information stored in the
calendar information storage section 57 will be described.
When the crown 3 is pulled out, the function processing section A53
makes the transition to the calendar information setting mode. When
the button 4 is held down in this state, the first processing
section A532A moves the first index 21 to sequentially indicate the
symbol 22, the character "M" representing the month, and the
character "L" representing the elapsed years. Further, when the
crown 3 is rotationally operated, the second processing section
A532B moves the second index 13.
Then, when the crown 3 is rotationally operated to move the second
index 13 and then the crown 3 is pushed in in the state in which
the first index 21 indicates the symbol 22, the calendar
information setting section A533 sets the value of the number
indicated by the second index 13 as the value of the day
information of the calendar information storage section 57.
Further, when the crown 3 is rotationally operated to move the
second index 13 and then the crown 3 is pushed in in the state in
which the first index 21 indicates the character "M" representing
the month, the calendar information setting section A533 sets the
value of the number indicated by the second index 13 as the value
of the month information of the calendar information storage
section 57.
Further, when the crown 3 is rotationally operated to move the
second index 13 and then the crown 3 is pushed in in the state in
which the first index 21 indicates the character "L" representing
the elapsed years, the calendar information setting section A533
sets the value of the number indicated by the second index 13 as
the value of the elapsed-year information of the calendar
information storage section 57.
Then, when the crown 3 is pushed in as described above, the
function processing section A53 makes the transition to the normal
mode.
Calendar Display Process
Then, the calendar display process performed by the calendar
display processing section A532 will be described.
FIG. 11 is a flowchart showing the calendar display process. The
calendar display process is performed while the function processing
section A53 is in the normal mode.
When the calendar display process is performed, the first
processing section A532A moves the first index 21 to indicate the
position corresponding to the charge amount in the symbol 22 to
thereby indicate the charge amount as shown in FIG. 9. Further,
thus, the first processing section A532A makes the first index 21
indicate the fact that the type of the calendar information is the
day. Further, the second processing section A5328 moves the second
index 13 to indicate the number corresponding to the value (1
through 31) of the day information stored in the calendar
information storage section 57 to thereby indicate the value of the
day information. Due to these operations, the day information is
displayed (AS11). It should be noted that this display state
corresponds to a display state in the normal period.
Then, the calendar display processing section A532 determines
whether or not the detection signal is input from the first switch
detection section 51 to thereby determine (AS12) whether or not the
button 4 has been held down.
In the case in which the determination of NO has been made in the
step AS12, the first processing section A532A and the second
processing section A532B continue the process of the step AS11. It
should be noted that in the case in which the time has passed while
the state of YES is not determined in the step AS12, and the value
of the day information stored in the calendar information storage
section 57 has been updated, the second processing section A532B
moves the second index 13 to indicate the value of the day
information having been updated.
On the other hand, in the case in which the determination of YES
has been made in the step AS12, the first processing section A532A
moves the first index 21 to indicate the character "M" representing
the month, and thus indicate the fact that the type of the calendar
information is the month as shown in FIG. 12. Further, the second
processing section A532B moves the second index 13 to indicate the
number corresponding to the value (1 through 12) of the month
information stored in the calendar information storage section 57
to thereby indicate the value of the month information. Due to
these operations, the month information is displayed (AS13).
Then, the calendar display processing section A532 determines
(AS14) whether or not the detection signal has been input from the
first switch detection section 51.
In the case in which the determination of NO has been made in the
step AS14, the first processing section A532A and the second
processing section A532B continue the process of the step AS13. It
should be noted that in the case in which the time has passed while
the state of YES is not determined in the step AS14, and the value
of the month information stored in the calendar information storage
section 57 has been updated, the second processing section A532B
moves the second index 13 to indicate the value of the month
information having been updated.
On the other hand, in the case in which the determination of YES
has been made in the step AS14, the first processing section A532A
moves the first index 21 to indicate the character "L" representing
the elapsed years, and thus indicate the fact that the type of the
calendar information is the elapsed years as shown in FIG. 13.
Further, the second processing section A532B moves the second index
13 to indicate the number corresponding to the value (0 through 3)
of the elapsed-year information stored in the calendar information
storage section 57 to thereby indicate the value of the
elapsed-year information. Due to these operations, the elapsed-year
information is displayed (AS15).
Then, the calendar display processing section A532 determines
(AS16) whether or not the detection signal has been output from the
first switch detection section 51.
In the case in which the determination of NO has been made in the
step AS16, the first processing section A532A and the second
processing section A532B continue the process of the step AS15. It
should be noted that in the case in which the time has passed while
the state of YES is not determined in the step AS16, and the value
of the elapsed-year information stored in the calendar information
storage section 57 has been updated, the second processing section
A532B moves the second index 13 to indicate the value of the
elapsed-year information having been updated.
On the other hand, in the case in which the determination of YES
has been made in the step AS16, the calendar display processing
section A532 returns the process to the step AS11, and then
repeatedly performs the processes of the steps AS11 through
AS16.
Functions and Advantages of Second Embodiment
The analog electronic watch A1 according to the second embodiment
can obtain substantially the same functions and advantages with
substantially the same configuration as that of the analog
electronic watch 1 according to the first embodiment.
Further, in the case in which the first index 21 indicates the
charge amount, the second index 13 indicates the value of the day
information. Therefore, it is possible for the user to check the
charge amount, and at the same time check the fact that the type of
the calendar information is the day by the first index 21
indicating the charge amount, and to check the day information
based on the value indicated by the second index 13. Therefore,
since the user can always check the value of the day and the charge
amount by keeping the first index indicating the charge amount, it
is possible to make the analog electronic watch A1 easier to
use.
Further, since the indication of the charge amount is performed by
the first index 21 for indicating the type of the calendar
information, there is no need to separately provide a dedicated
index to the indication of the charge amount, the number of the
indexes provided to the analog electronic watch A1 can be decreased
compared to the case of separately providing the dedicated index.
Thus, the number of step motors and gears can also be reduced.
Third Embodiment
In an analog electronic watch according to a third embodiment, the
first processing section A532A makes the first index 21 indicate
the charge amount in the case in which the charge amount detected
by the charge amount detection section 58 becomes lower than a
threshold value set in advance. The rest of the configuration is
the same as that of the analog watch A1 according to the second
embodiment.
FIG. 14 is a flowchart showing the calendar display process in the
third embodiment. Here, the steps AS11 through AS16 are the same as
those of the calendar display process of the second embodiment, and
therefore, the explanation thereof will be omitted.
In the calendar display process of the second embodiment, after the
process of the step AS11, the first processing section A532A
determines whether or not the charge amount detected by the charge
amount detection section 58 is lower than the threshold value set
in advance, and then makes the process proceed to the step AS12 in
the case in which the state of NO has been determined, or returns
the process to the step AS11 in the case in which the determination
of YES has been made (AS21).
Similarly, after the process of the step AS13, the first processing
section A532A determines whether or not the charge amount is lower
than the threshold value, and then makes the process proceed to the
step AS14 in the case in which the state of NO has been determined,
or returns the process to the step AS11 in the case in which the
determination of YES has been made (AS22). Further, after the
process of the step AS15, whether or not the charge amount is lower
than the threshold value is determined, and the process proceeds to
the step AS16 in the case in which the state of NO has been
determined, or the process is returned to the step AS11 in the case
in which the determination of YES has been made (AS23).
According to this operation, even in the case in which the first
index 21 indicates the character "M" representing the month or the
character "L" representing the elapsed years, if the charge amount
becomes lower than the threshold value, the determination of YES is
made in the steps AS22 and AS23, the process returns to the step
AS11, the first index 21 indicates the charge amount, and the
second index 13 indicates the value of the day information.
Further, in the case in which the charge amount becomes lower than
the threshold value in the state in which the first index 21
indicates the charge amount, since the state of YES is always
determined in the step AS21, and the processes of the steps AS11,
AS21 are repeated, even if the button 4 is held down, the first
index 21 continuously indicates the charge amount.
It should be noted that the process of the step AS21 can also be
eliminated. In this case, in the case in which the charge amount
becomes lower than the threshold value in the state in which the
first index 21 indicates the charge amount, if the button 4 is held
down, the month information is displayed in the step AS13. Then,
immediately afterwards, the determination of YES is made in the
step AS22, the process returns to the step AS11, and the first
index 21 indicates the charge amount.
Functions and Advantages of Third Embodiment
Even in the case in which the first index 21 does not indicate the
charge amount, if the charge amount of the secondary cell 5 drops
to a level lower than the threshold value, the first index 21
automatically indicates the charge amount, and therefore, the user
can check the fact that the charge amount has dropped. Thus, it is
possible to surely inform the user of the fact that the charge
amount of the secondary cell 5 has dropped to thereby reduce the
possibility that the charge fails to occur to cause a system
failure.
Fourth Embodiment
An analog electronic watch A1A according to a fourth embodiment is
provided with an alarm function as an additional function other
than the calendar display function.
FIG. 15 is a front view showing the analog electronic watch A1A. It
should be noted that the same constituents as those of the analog
electronic watch A1 according to the second embodiment are provided
with the same reference symbols, and the explanation thereof will
be omitted.
In the analog electronic watch A1A, in the periphery of the first
small window A20, the character of "M" representing the month is
displayed in the vicinity of the 5 o'clock position of the first
small window A20, and the character of "L" representing the elapsed
years is displayed in the vicinity of the 7 o'clock position of the
first small window A20. Further, the characters of "S," "M," "T,"
"W," "T," "F," and "S" respectively representing the seven days of
the week of Sunday through Saturday are displayed in the vicinity
of the 1 o'clock position through the vicinity of the 4 o'clock
position of the first small window A20. Further, in the vicinity of
the 12 o'clock position of the first small window A20, there are
displayed characters of "AL" representing the alarm function.
The first index 21 indicates one of the characters "S" through "S"
representing the seven days of the week to thereby indicate the day
of the week.
Further, the first index 21 indicates the type of the additional
function other than the calendar display function. In the present
embodiment, the first index 21 indicates the characters "AL" to
thereby indicate the alarm function.
Further, the first index 21 indicates either of the symbol 22 and
the characters "S" through "S" and "AL" to thereby indicate the
fact that the type of the calendar information is the day.
Further, in the analog electronic watch A1A, the second small
window 30 is disposed at a position shifted toward the 9 o'clock
direction from the center of the dial plate A2. Further, at the
position shifted toward the 6 o'clock direction from the center of
the dial plate A2, there is disposed a third small window 60 having
a circular shape.
Further, in the third small window 60, there are disposed a first
function hand 61 and a second function hand 62. The function hands
61, 62 respectively indicate the hour and the minute of the alarm
time. The first function hand 61 indicates the hour of the alarm
time, and the second function hand 62 indicates the minute of the
alarm time. Here, the function hands 61, 62 each constitute a third
index according to the invention.
FIG. 16 is a block diagram showing a configuration of the analog
electronic watch A1A.
As shown in FIG. 16, the function hands 61, 62 are driven by a step
motor 45 for the function hands. Further, a drive control circuit
A50A is provided with a function hand drive control section 59, and
the function hand drive control section 59 outputs a motor drive
pulse using the reference signal output from the reference signal
generation circuit to control the step motor 45 for the function
hands to thereby control the drive of the function hands 61,
62.
In the analog electronic watch A1A, when the button 4 is held down,
the first processing section A532A moves the first index 21 to make
the first index 21 indicate the days of the week, the character "M"
representing the month, the character "L" representing the elapsed
years, the charge amount, and the characters "AL" representing the
alarm function in a switching manner.
It should be noted that the first processing section A532A makes
the first index 21 indicate the character corresponding to the
day-of-the-week information stored in the calendar information
storage section 57 out of the characters "S" through "S"
representing the seven days of the week to thereby indicate the
clay of the week.
Further, the function processing section A53A of the analog
electronic watch A1A is provided with an alarm function section
A535.
When the current time reaches the alarm time set in advance, the
alarm function section A535 detects the fact that the current time
has reached the alarm time, and then informs the user of the fact
using a sounding device not shown provided to the analog electronic
watch A1A.
Further, the alarm function section A535 controls the step motor 45
for the function hands to thereby control the movement of the
function hands 61, 62.
Specifically, in the case in which the first index 21 indicates the
characters "AL," the alarm function section A535 makes the function
hands 61, 62 indicate the hour and the minute of the alarm time set
in advance. It should be noted that in the case in which the first
index 21 indicates characters or symbols other than the characters
"AL," the time display processing section A531 makes the function
hands 61, 62 indicate the hour and the minute of the current
time.
It should be noted that the alarm time can be set by, for example,
making the first index 21 indicate the characters "AL," and then
rotationally operating the crown 3 to make the function hands 61,
62 indicate predetermined time in this state.
Calendar Display Process
FIGS. 17 and 18 are flowcharts showing a calendar display process
in the fourth embodiment.
When the calendar display process is performed, the first
processing section A532A moves the first index 21 to indicate the
character corresponding to the day-of-the-week information stored
in the calendar information storage section 57 out of the
characters "S" through "S" representing the seven days of the week
to thereby indicate the day of the week. Further, thus, the first
processing section A532A makes the first index 21 indicate the fact
that the type of the calendar information is the day. Further, the
second processing section A532B moves the second index 13 to
indicate the number corresponding to the value of the day
information stored in the calendar information storage section 57
to thereby indicate the value of the day information. Further, the
time display processing section A531 makes the function hands 61,
62 indicate (AS31) the hour and the minute of the current time. It
should be noted that this display state corresponds to a display
state in the normal period.
Then, the function processing section A53A determines (AS32)
whether or not the button 4 has been held down. In the case in
which the determination of NO has been made in the step AS32, the
function processing section A53A returns the process to the step
AS31.
In the case in which the determination of YES has been made in the
step AS32, the first processing section A532A moves the first index
21 to indicate the character "M" representing the month. Further,
the second processing section A532B moves the second index 13 to
indicate (AS33) the number corresponding to the value of the month
information stored in the calendar information storage section
57.
Then, the function processing section A53A determines (AS34)
whether or not the button 4 has been held down. In the case in
which the determination of NO has been made in the step AS34, the
function processing section A53A returns the process to the step
AS33.
In the case in which the determination of YES has been made in the
step AS34, the first processing section A532A moves the first index
21 to indicate the character "L" representing the elapsed years.
Further, the second processing section A532B moves the second index
13 to indicate (AS35) the number corresponding to the value of the
elapsed-year information stored in the calendar information storage
section 57.
Then, the function processing section A53A determines (AS36)
whether or not the button 4 has been held down. In the case in
which the determination of NO has been made in the step AS36, the
function processing section A53A returns the process to the step
AS35.
In the case in which the determination of YES has been made in the
step AS36, the first processing section A532A moves the first index
21 to indicate the charge amount. Further, the second processing
section A532B moves the second index 13 to indicate (AS37) the
number corresponding to the value of the day information stored in
the calendar information storage section 57.
Then, the function processing section A53A determines (AS38)
whether or not the button 4 has been held down. In the case in
which the determination of NO has been made in the step AS38, the
function processing section A53A returns the process to the step
AS37.
In the case in which the determination of YES has been made in the
step AS38, the first processing section A532A moves the first index
21 to indicate the characters "AL" to thereby indicate the fact
that the type of the additional function is the alarm function.
Further, the second processing section A532B moves the second index
13 to indicate the number corresponding to the value of the day
information stored in the calendar information storage section 57.
Further, the alarm function section A535 makes the function hands
61, 62 indicate (AS39) the hour and the minute of the alarm time
set in advance.
Then, the function processing section A53A determines (AS40)
whether or not the button 4 has been held down, and then returns
the process to the step AS39 in the case in which the determination
of NO has been made, or returns the process to the step AS31, and
then repeatedly performs the processes of the steps AS31 through
AS40 in the case in which the determination of YES has been
made.
Functions and Advantages of Fourth Embodiment
In the case in which the first index 21 indicates the day of the
week, the second index 13 indicates the value of the day.
Therefore, it is possible for the user to check the day of the
week, and at the same time check the fact that the type of the
calendar information is the day by the first index 21 indicating
the day of the week, and to check the day information based on the
value indicated by the second index 13. Thus, it is possible to
make the analog electronic watch A1A easier to use. Further, since
there is no need to separately provide a dedicated index to the
indication of the day of the week, the number of the indexes
provided to the analog electronic watch A1A can be decreased
compared to the case of separately providing the dedicated
index.
Further, by checking the fact that the first index 21 indicates the
characters "AL," the user can confirm the fact that the function
hands 61, 62 indicate the alarm time.
Further, since the second index 13 indicates the value of the day
information while the first index 21 is indicating the characters
"AL," the user can check the alarm time and the day information at
the same time.
Fifth Embodiment
An analog electronic watch according to a fifth embodiment performs
the following process in addition to the process of the analog
electronic watch A1A according to the fourth embodiment. In other
words, in the case in which the charge amount detected by the
charge amount detection section 58 becomes lower than the threshold
value set in advance, the first processing section A532A makes the
first index 21 indicate the charge amount, and restricts the
operation of the alarm function section A535.
FIGS. 19 and 20 are flowcharts showing a calendar display process
in the fifth embodiment. Here, the steps AS31 through AS40 are the
same as those of the calendar display process of the fourth
embodiment, and therefore, the explanation thereof will be
omitted.
In the calendar display process of the fifth embodiment, the first
processing section A532A determines whether or not the charge
amount detected by the charge amount detection section 58 is lower
than the threshold value set in advance after the process of the
step AS31. Then, in the case in which the determination of NO has
been made, the first processing section A532A makes the process
proceed to the step AS32 to determine whether or not the button 4
has been held down. On the other hand, in the case in which the
determination of YES has been made, the first processing section
makes (AS51) the process proceed to the step AS56.
Further, the first processing section A532A also performs (AS52
through AS55) substantially the same determination after the
processes of the steps AS33, AS35, AS37, and AS39.
In the step AS56, the first processing section A532A restricts the
operation of the alarm function section A535. In other words, the
first processing section A532A terminates the operation of the
alarm function section A535 in the case in which the alarm function
section A535 is in operation, or inhibits the alarm function
section A535 from operating in the case in which the alarm function
section A535 is not in operation. Further, the first processing
section A532A makes the process proceed to the step AS37. Then, the
first processing section A532A makes the first index 21 indicate
the charge amount.
It should be noted that in the case in which the secondary cell 5
is charged, and the charge amount detected by the charge amount
detection section 58 has become equal to or higher than the
threshold value after restricting the operation of the alarm
function section A535, the first processing section A532A remove
the restriction.
Further, the process of the step AS54 can also be eliminated
similarly to the process of the step AS21 of the third
embodiment.
Functions and Advantages of Fifth Embodiment
Even in the case in which the first index 21 does not indicate the
charge amount, if the charge amount of the secondary cell 5 drops
to a level lower than the threshold value, the first index 21
automatically indicates the charge amount, and therefore, the user
can check the fact that the charge amount has dropped. Thus, it is
possible to surely inform the user of the fact that the charge
amount of the secondary cell 5 has dropped to thereby reduce the
possibility that the charge fails to occur to cause a system
failure.
Further, since the execution of the alarm function is restricted if
the charge amount drops to a level lower than the threshold value,
the power consumption can be reduced compared to the case in which
the restriction is not applied, and the possibility of the system
failure can further be reduced. Further, the situation that the
alarm function is not correctly performed can be prevented from
occurring.

the invention. It should be noted that one of the function hands
61, 62 can also be formed of a twenty-four-hour hand.
FIG. 22 is a block diagram showing a configuration of the analog
electronic watch B1.
As shown in FIG. 22, the indexes 11 through 13, 21, 31, 61, and 62
are respectively driven by five step motors. Specifically, the
second hand 31 is driven by the step motor 41 for the second hand,
the hour hand 11 and the minute hand 12 are driven by the step
motor 42 for the hour hand and the minute hand, the first index 21
is driven by the step motor 43 for the first index, the second
index 13 is driven by the step motor 44 for the second index, and
the function hands 61, 62 are driven the step motor 45 for the
function hands. Here, the step motor 43 for the first index
constitutes the first drive unit according to the invention, the
step motor 44 for the second index constitutes the second drive
unit according to the invention, and the step motor 45 for the
function hands constitutes a third drive unit according to the
invention. It should be noted that it is also possible for the
second hand 31, the hour hand 11, and the minute hand 12 to be
driven by a common step motor. Further, it is also possible for the
first function hand 61 and the second function hand 62 to be driven
by respective step motors.
In order to perform the drive control of each of the step motors 41
through 45, a drive control circuit B50 is incorporated in the
analog electronic watch B1.
The drive control circuit B50 is provided with a first switch
detection section 51A, the second switch detection section 52, a
third switch detection section 51B, a function processing section
B53, the time hand drive control section 54, the first index drive
control section 55, the second index drive control section 56, the
function hand drive control section 59, and the calendar
information storage section 57.
The first switch detection section 51A detects a push-in operation
of the button 4, and outputs the detection signal to the function
processing section 53 in the case in which the push-in operation
has occurred. Here, the first switch detection section 51A
constitutes the detection section according to the invention.
The third switch detection section 51B detects a push-in operation
of the button 7, and outputs the detection signal to the function
processing section 53 in the case in which the push-in operation
has occurred.
The function hand drive control section 59 outputs a motor drive
pulse using the reference signal output from the reference signal
generation circuit to control the step motor 45 for the function
hands to thereby control the drive of the function hands 61,
62.
The function processing section B53 is provided with a time display
processing section B531, a calendar display processing section
B532, a calendar information setting section B533, and a calendar
information update section B534, and is further provided with an
alarm function section B535 and a chronograph function section B536
as function sections for performing the additional functions other
than the calendar display function.
The time display processing section B531 is for displaying the
hour, the minute, and the second of the current time with the hour
hand 11, the minute hand 12, and the second hand 31 using the time
hand drive control section 54. Further, it is also possible for the
time display processing section B531 to control the function hand
drive control section 59 to display the hour and the minute of the
current time with the function hands 61, 62.
The calendar information setting section B533 and the calendar
information update section B534 have substantially the same
functions as those of the calendar information setting section 533
and the calendar information update section 534 of the analog
electronic watch 1 according to the first embodiment.
The calendar display processing section B532 is provided with a
first processing section B532A and a second processing section
B532B.
The first processing section B532A controls the step motor 43 for
the first index to thereby control the movement of the first index
21.
Specifically, when the button 4 is held down and the detection
signal is input from the first switch detection section 51A, the
first processing section B532A moves the first index 21 to make the
first index 21 indicate the days of the week, the character "M"
representing the month, the character "L" representing the elapsed
years, the characters "AL" representing the alarm function, and the
characters "CHR" representing the chronograph function in a
switching manner.
Here, when making the first index 21 indicate the day of the week,
the first processing section B532A makes the first index 21
indicate the character corresponding to the day-of-the-week
information stored in the calendar information storage section 57
out of the characters "S" through "S" representing the seven days
of the week to thereby indicate the day of the week.
The second processing section B532B controls the step motor 44 for
the second index to thereby control the movement of the second
index 13.
Specifically, when the type of the calendar information to be
indicated by the first index 21 has been switched, the second
processing section B532B makes the second index 13 indicate the
number corresponding to the value of the type of the calendar
information to be indicated by the first index 21 out of the
calendar information stored in the calendar information storage
section 57 to thereby indicate the value of the calendar
information.
When the current time reaches the alarm time set in advance, the
alarm function section B535 detects the fact that the current time
has reached the alarm time, and then informs the user of the fact
using a sounding device not shown provided to the analog electronic
watch B1.
Further, the alarm function section B535 controls the step motor 45
for the function hands to thereby control the movement of the
function hands 61, 62.
Specifically, in the case in which the first index 21 indicates the
characters "AL," the alarm function section B535 makes the function
hands 61, 62 indicate the hour and the minute of the alarm time set
in advance.
It should be noted that the alarm time can be set by, for example,
making the first index 21 indicate the characters "AL," and then
rotationally operating the crown 3 to make the function hands 61,
62 indicate predetermined time in this state.
In the case in which the first index 21 indicates the characters
"CHR," the chronograph function section B536 controls the step
motor 45 for the function hands to control the movements of the
function hands 61, 62 to thereby indicate the measured time of the
chronograph function.
Further, when the button 7 is held down in the state in which the
first index 21 indicates the characters "CHR," the chronograph
function section B536 starts the time measurement. Then, the
chronograph function section B536 stops the measurement when the
button 7 is held down again, and resets the measured time when the
button 4 is held down in the state in which the measurement
stops.
Calendar Information Setting Process
The process of setting the calendar information in the present
embodiment is substantially the same as that of the first
embodiment. It should be noted that in the present embodiment,
although the second index 13 is moved by the crown 3 being
rotationally operated in the calendar information setting mode, it
is also possible to arrange that the second index 13 is moved by,
for example, the button 7 being pushed in.
Calendar Display Process
Then, the calendar display process will be described.
FIGS. 23 and 24 are flowcharts showing the calendar display
process. The calendar display process is performed while the
function processing section B53 is in the normal mode.
When the calendar display process is performed, the first
processing section B532A moves the first index 21 to indicate the
character corresponding to the day-of-the-week information stored
in the calendar information storage section 57 out of the
characters "S" through "S" representing the seven days of the week
to thereby indicate the day of the week as shown in FIG. 21.
Further, thus, the first processing section B532A makes the first
index 21 indicate the fact that the type of the calendar
information is the day. Further, the second processing section
B532B moves the second index 13 to indicate the number
corresponding to the value (1 through 31) of the day information
stored in the calendar information storage section 57 to thereby
indicate the value of the day information. Due to these operations,
the day information is displayed. It should be noted that in the
example shown in FIG. 21, there is displayed the 20.sup.th day.
Further, the time display processing section B531 makes the
function hands 61, 62 indicate (BS11) the hour and the minute of
the current time. It should be noted that this display state
corresponds to a display state in the normal period.
Then, the function processing section B53 determines whether or not
the detection signal is input from the first switch detection
section 51A to thereby determine (BS12) whether or not the button 4
has been held down.
In the case in which the determination of NO has been made in the
step BS12, the function processing section B53 continues the
process of the step BS11. It should be noted that in the case in
which the time has passed while the determination of YES is not
made in the step BS12, and the value of the day information and the
day-of-the-week information stored in the calendar information
storage section 57 have been updated, the first processing section
B532A moves the first index 21 to indicate the day of the week
having been updated, and the second processing section B532B moves
the second index 13 to indicate the value of the day information
having been updated.
On the other hand, in the case in which the determination of YES
has been made in the step BS12, the first processing section B532A
moves the first index 21 to indicate the character "M" representing
the month, and thus indicate the fact that the type of the calendar
information is the month as shown in FIG. 25. Further, the second
processing section B532B moves the second index 13 to indicate the
number corresponding to the value (1 through 12) of the month
information stored in the calendar information storage section 57
to thereby indicate the value of the month information. Due to
these operations, the month information is displayed (BS13). It
should be noted that in the example shown in FIG. 25, there is
displayed December.
Then, the function processing section B53 determines (BS14) whether
or not the detection signal has been input from the first switch
detection section 51A.
In the case in which the determination of NO has been made in the
step BS14, the function processing section B53 continues the
process of the step BS13. It should be noted that in the case in
which the time has passed while the determination of YES is not
made in the step BS14, and the value of the month information
stored in the calendar information storage section 57 has been
updated, the second processing section B532B moves the second index
13 to indicate the value of the month information having been
updated.
On the other hand, in the case in which the determination of YES
has been made in the step BS14, the first processing section B532A
moves the first index 21 to indicate the character "L" representing
the elapsed years, and thus indicate the fact that the type of the
calendar information is the elapsed years as shown in FIG. 26.
Further, the second processing section B532B moves the second index
13 to indicate the number corresponding to the value (0 through 3)
of the elapsed-year information stored in the calendar information
storage section 57 to thereby indicate the value of the
elapsed-year information. Due to these operations, the elapsed-year
information is displayed (BS15). It should be noted that in the
example shown in FIG. 26, there is displayed +2 years.
Then, the function processing section B53 determines (BS16) whether
or not the detection signal has been output from the first switch
detection section 51A.
In the case in which the determination of NO has been made in the
step BS16, the function processing section B53 continues the
process of the step BS15. It should be noted that in the case in
which the time has passed while the determination of YES is not
made in the step BS16, and the value of the elapsed-year
information stored in the calendar information storage section 57
has been updated, the second processing section B532B moves the
second index 13 to indicate the value of the elapsed-year
information having been updated.
On the other hand, in the case in which the determination of YES
has been made in the step BS16, the first processing section B532A
moves the first index 21 to indicate the characters "AL," and thus
indicate the alarm function as shown in FIG. 27. Further, the
second processing section B532B moves the second index 13 to
indicate the number corresponding to the value of the day
information stored in the calendar information storage section 57.
Further, the alarm function section B535 makes the function hands
61, 62 indicate (BS17) the hour and the minute of the alarm time
set in advance.
Then, the function processing section B53 determines (BS18) whether
or not the detection signal has been output from the first switch
detection section 51A.
In the case in which the determination of NO has been made in the
step BS18, the function processing section B53 continues the
process of the step BS17. It should be noted that in the case in
which the time has passed while the determination of YES is not
made in the step BS18, and the value of the day information stored
in the calendar information storage section 57 has been updated,
the second processing section B532B moves the second index 13 to
indicate the value of the day information having been updated.
On the other hand, in the case in which the determination of YES
has been made in the step B318, the first processing section B532A
moves the first index 21 to indicate the characters "CHR," and thus
indicate the chronograph function as shown in FIG. 28. Further, the
chronograph function section B536 makes the function hands 61, 62
indicate the hour and the minute of the measured time (BS19). It
should be noted that by driving the function hands 61, 62 with the
respective step motors, it is possible to make the function hands
61, 62 indicate the minute and the second of the measured time.
Then, the function processing section B53 determines (BS20) whether
or not the detection signal has been output from the first switch
detection section 51A.
In the case in which the determination of NO has been made in the
step BS20, the function processing section B53 continues the
process of the step BS19. It should be noted that in the case in
which the time has passed while the determination of YES is not
made in the step BS20, and the value of the day information stored
in the calendar information storage section 57 has been updated,
the second processing section B532B moves the second index 13 to
indicate the value of the day information having been updated.
On the other hand, in the case in which the determination of YES
has been made in the step S20, the function processing section B53
returns the process to the step BS11, and then repeatedly performs
the processes of the steps BS11 through BS20.
Method of Moving Second Index
Then, the method of moving the second index 13 by the second
processing section B532B will be described.
The second processing section B532B moves the second index 13 in
the following manner when the time has passed, the value of the
calendar information stored in the calendar information storage
section 57 has been updated, and the second index 13 is made to
indicate the next value, or when the crown 3 has been rotationally
operated in the calendar information setting mode, and the second
index 13 is made to indicate the next value.
Firstly, the case in which the first index 21 is indicating the day
of the week, the characters "AL," or the characters "CHR" will be
described. In this case, in the case in which the second index 13
indicates either of the numbers of 1 through 30, the second index
13 is rotated clockwise (normal rotation) viewed from the obverse
side of the watch to indicate the next number. Further, in the case
in which the second index 13 indicates the number of 31, the second
index 13 is made to rotate clockwise to indicate the number of 1
after passing through the position of indicating the number of 0
with fast-forwarding.
Then, the case in which the first index 21 is indicating the
character "M" representing the month will be described. In this
case, in the case in which the second index 13 indicates either of
the numbers of 1 through 11, the second index 13 is rotated
clockwise to indicate the next number. Further, in the case in
which the second index 13 indicates the number of 12, the second
index 13 is made to rotate counterclockwise (reverse rotation) to
indicate the number of 1 after passing through the positions of
indicating the numbers of 2 through 11.
Then, the case in which the first index 21 is indicating the
character "L" representing the elapsed years will be described. In
this case, in the case in which the second index 13 indicates
either of the numbers of 0 through 2, the second index 13 is
rotated clockwise to indicate the next number. Further, in the case
in which the second index 13 indicates the number of 3, the second
index 13 is made to rotate counterclockwise to indicate the number
of 0 after passing through the positions of indicating the numbers
of 1 and 2.
Functions and Advantages of Sixth Embodiment
The analog electronic watch B1 according to the sixth embodiment
can obtain substantially the same functions and advantages with
substantially the same configuration as that of the analog
electronic watch 1 according to the first embodiment.
Further, when the user operates the button 4 to make the first
index 21 indicate one of the types of the functions, the function
hands 61, 62 indicate the information related to the type of the
function indicated by the first index 21. Therefore, by checking
the type of the function indicated by the first index 21, the user
can check what function is related to the information indicated by
the function hands 61, 62.
Further, since the second index 13 indicates the value of the day
information while the first index 21 is indicating the type of the
function, the user can check the information related to the
function and the day information at the same time.
The user can check the alarm time based on the indication of the
function hands 61, 62 by operating the button 4 to make the first
index 21 indicate the alarm function. Further, by making the first
index 21 indicate the chronograph function, the user can check the
measured time of the chronograph function based on the indication
of the function hands 61, 62.
Further, since the function hands 61, 62 indicate the hour and the
minute of the current time in the case in which the first index 21
does not indicate the alarm function or the chronograph function,
it is possible to check the hour and the minute of the current time
using the function hands 61, 62.
Since the alarm time and the measured time of the chronograph
function are indicated by the function hands 61, 62, the number of
indexes provided to the analog electronic watch B1 can be reduced
compared to the case of providing a dedicated index to the
indication of the alarm time and a dedicated index to the
indication of the measured time. Thus, the number of step motors
and gears can also be reduced. Further, since the indication area
can be enlarged, the alarm time and the measured time can be
displayed in an easy-to-understand manner.
Seventh Embodiment
An analog electronic watch B1A according to a seventh embodiment of
the invention is provided with a timer function for measuring the
time based on the time set in advance in a countdown manner instead
of the chronograph function with respect to the analog electronic
watch B1 according to the sixth embodiment.
FIG. 29 is a front view showing the analog electronic watch B1A. It
should be noted that the same constituents as those of the analog
electronic watch B1 according to the sixth embodiment are provided
with the same reference symbols, and the explanation thereof will
be omitted.
As shown in FIG. 29, in the analog electronic watch B1A, characters
of "TM" representing the timer function are displayed in the
vicinity of the 12 o'clock position of the first small window B20
in the periphery of the first small window B20.
The first index 21 indicates the characters "TM" to thereby
indicate the timer function.
Further, in the outer periphery of the third small window 60, there
are displayed numbers of "0," "15," "30," and "45" representing the
remaining time (minute) of the timer function.
The function hands 61, 62 indicate the measured time of the timer
function.
In the seventh embodiment, the function processing section B53 is
provided with a timer function section as the function section for
performing an additional function other than the calendar display
function. In the case in which the first index 21 indicates the
characters "TM," the timer function section makes the function
hands 61, 62 indicate the minute and the second of the measured
time of the timer function. It should be noted that in the seventh
embodiment, the function hands 61, 62 are driven by the respective
step motors.
Further, when the button 7 is held down in the state in which the
first index 21 indicates the characters "TM," the timer function
section starts the time measurement from the time set in advance in
a countdown manner. Then, the timer function section stops the
measurement when the button 7 is held down again, and resets the
measured time when the button 4 is held down in the state in which
the measurement stops.
The time of the time function can be set by making the first index
21 indicate the characters "TM," and then rotationally operating
the crown 3 to make the function hands 61, 62 indicate
predetermined time in this state.
It should be noted that the analog electronic watch B1A can also be
provided with the chronograph function in addition to the timer
function.
Further, in the analog electronic watch B1A, the function hand can
be formed of a single index for indicating the minute of the
measured time of the timer function.
Functions and Advantages of Seventh Embodiment
According also to the seventh embodiment, substantially the same
functions and advantages can be obtained with substantially the
same configuration as that of the sixth embodiment.
Further, the user can check the measured time of the timer function
based on the indication of the function hands 61, 62 by operating
the button 4 to make the first index 21 indicate the timer
function.
Eighth Embodiment
An analog electronic watch B1B according to an eighth embodiment of
the invention is provided with a dual time display function capable
to displaying two different times instead of the chronograph
function with respect to the analog electronic watch B1 according
to the sixth embodiment.
FIG. 30 is a front view of the analog electronic watch B1B. As
shown in FIG. 30, in the analog electronic watch B1B, characters of
"DT" representing the dual time display function are displayed in
the vicinity of the 12 o'clock position of the first small window
B20 in the periphery of the first small window B20.
The first index 21 indicates the characters "DT" to thereby
indicate the dual time display function.
In the eighth embodiment, the function processing section B53 is
provided with a dual time display function section as the function
section for performing an additional function other than the
calendar display function. In the case in which the first index 21
indicates the characters "DT," the dual time display function
section makes the function hands 61, 62 indicate the hour and the
minute of the set time.
It should be noted that the set time is set by the user operating
the buttons 4, 7 and the crown 3 to make the function hands 61, 62
indicate arbitrary time.
Further, it is also possible to arrange that by displaying the
names of cities from all over the world on the inner peripheral
side or the outer peripheral side of the numbers of 1 through 31 on
the dial plate B2, and the user operating the buttons 4, 7 and the
crown 3 to make the second index 13 indicate the name of an
arbitrary city, the local time of the city thus indicated is set as
the set time. It should be noted that such a function is called a
world time function.
It should be noted that the analog electronic watch B1B can also be
provided with either one of or both of the chronograph function and
the timer function in addition to the dual time display
function.
Functions and Advantages of Eighth Embodiment
According also to the eighth embodiment, substantially the same
functions and advantages can be obtained with substantially the
same configuration as that of the sixth embodiment.
Further, the user can check the set time of the dual time display
function based on the indication of the function hands 61, 62 by
operating the button 4 to make the first index 21 indicate the dual
time display function.
Ninth Embodiment
In an analog electronic watch B1C according to a ninth embodiment
of the invention, compared to the analog electronic watch B1
according to the sixth embodiment, in the case in which the first
index 21 indicates the characters "CHR," the chronograph function
section B536 makes not only the function hands 61, 62 but also the
second index 13 indicate the measured time. Specifically, the
chronograph function section B536 makes the function hands 61, 62
indicate the hour and the minute of the measured time, and makes
the second index 13 indicate the second of the measured time.
FIG. 31 is a front view of the analog electronic watch B1C. As
shown in FIG. 31, in the analog electronic watch B1C, a scale and
numbers representing the measured time of the chronograph function
are displayed on the outer peripheral side of the numbers of 1
through 31 on the dial plate B2. It should be noted that these
scale and numbers can also be displayed on the inner peripheral
side of the numbers of 1 through 31.
The second index 13 indicates these scale and numbers to thereby
indicate the second of the measured time of the chronograph
function.
Further, the second index 13 is indicating the 12 o'clock position
of the dial plate B2 before the measurement is started. On this
occasion, the characters "CHR" representing the chronograph
function are displayed in the vicinity of the 11 o'clock position
of the first small window B20 so as not to be covered by the second
index 13.
Functions and Advantages of Ninth Embodiment
According also to the ninth embodiment, substantially the same
functions and advantages can be obtained with substantially the
same configuration as that of the sixth embodiment.
Further, by making the function hands 61, 62 display the hour and
the minute of the measured time of the chronograph function, and
making the second index 13 indicate the second of the measured
time, it is possible to indicate the hour, the minute, and the
second of the measured time.
Other Embodiments
It should be noted that the invention is not limited to the
embodiments described above, but can be implemented with a variety
of modifications within the scope or the spirit of the
invention.
Although in each of the embodiments described above, the first
index 21 is configured so as to be able to indicate the fact that
the type of the calendar information is one of the day, the month,
and the elapsed years, the invention is not limited to this
configuration. For example, the first index 21 can also be
configured so as to be able to indicate only the day and the month.
In this case, it is sufficient for the second index 13 to be
configured so as to be able to indicate the numbers of 1 through
31.
Although in the first, and fourth through ninth embodiments
described above, the first index 21 indicates the day of the week
to thereby indicate the fact that the type of the calendar
information is the day, the invention is not limited to this
configuration. It is also possible to arrange that the fact that
the type of the calendar information is the day is indicated by,
for example, displaying the symbol representing the day in the
periphery of the first small window, and making the first index 21
indicate the symbol.
Although in each of the embodiments described above, the second
index 13 indicates the numbers of 0 through 31 to thereby indicate
the value of the calendar information, the invention is not limited
to this configuration. It is also possible to indicate the value of
the calendar information by indicating, for example, the symbols
corresponding to the numbers 0 through 31.
Although in each of the embodiments described above, the movement
range of the second index 13 is limited in the case in which the
first index 21 indicates the month and the elapsed years, the
invention is not limited to this configuration. In other words, the
movement range is not required to be limited.
In this case, the second index 13 moves through the positions of
indicating the numbers 0 and 13 through 31 with fast-forwarding in
the case in which the first index 21 indicates the month, or moves
through the positions of indicating the numbers 4 through 31 with
fast-forwarding in the case in which the first index 21 indicates
the elapsed years. It should be noted that in the case in which the
first index 21 indicates the day, the second index 13 moves the
position of indicating the number 0 with fast-forwarding.
According to this configuration, since the second index 13 moves
through the positions of indicating the values, which are not the
setting target, with fast-forwarding in the calendar information
setting process, setting of the values of the calendar information
can promptly be performed compared to the case in which the second
index 13 does not move with fast-forwarding.
Although in each of the embodiments, when the type of the calendar
information indicated by the first index 21 is switched, the second
processing section makes the second index 13 indicate the value of
the type of the calendar information indicated by the first index
21 in conjunction therewith, the invention is not limited to this
configuration.
In other words, the second processing section is not required to
perform the movement of the second index 13 in conjunction with the
first index 21.
For example, it is also possible to arrange that the switching of
the indication position of the first index 21 is performed in the
state in which the crown 3 is pulled out, and the second processing
section moves the second index at the timing when the crown 3 is
pushed in.
Although in the first and fourth through ninth embodiments, the
first index 21 indicates either of the characters "S" through "S"
representing the seven days of the week to thereby display the day
of the week, the invention is not limited to this
configuration.
It is also possible to display the day of the week by, for example,
displaying a symbol representing the fact that the type of the
calendar information is the day of the week in the periphery of the
first small window, making the first index 21 indicate the symbol,
and at the same time making the second index 13 indicate the value
of the day of the week.
Although in each of the embodiments described above, the value of
the calendar information is indicated by the second index 13, the
invention is not limited to this configuration.
For example, it is also possible to arrange that the second hand 31
indicates the value of the calendar information. The second hand 31
is smaller in movement range than the second index 13, which is a
center hand, but can sufficiently indicate the values of 0 through
31 in a recognizable range for the user.
Although in each of the embodiments described above, the calendar
information stored in the calendar information storage section 57
is set by the calendar information setting process, the invention
is not limited to this configuration.
It is also possible to set the calendar information by externally
receiving a radio wave including the calendar information such as a
time calibration signal or a satellite signal transmitted from a
GPS (global positioning system) satellite.
Although in the second through fifth embodiments described above,
the second index 13 indicates the value of the day information in
the case in which the first index 21 indicates the charge amount,
the day of the week, or the characters "AL," the invention is not
limited to this configuration. Specifically, in this case, it is
also possible for the second index 13 to indicate the value of the
month information, the value of the elapsed-year information, or
other information instead of the value of the day information. It
should be noted that in this case, it is sufficient to display a
symbol representing the day in the periphery of, for example, the
first small window A20, and to arrange that in the case in which
the first index 21 indicates the symbol, the second index 13
indicates the value of the day information.
Although in the fourth and fifth embodiments described above, in
the case in which the first index 21 indicates the day of the week,
the character "M" representing the month, or the character "L"
representing the elapsed years, the function hands 61, 62 indicate
the hour and the minute of the current time, the invention is not
limited to this configuration. It is also possible for the function
hands 61, 62 to indicate, for example, the alarm time.
The analog electronic watch according to each of the fourth and
fifth embodiments described above is provided with the alarm
function as an additional function other than the calendar display
function, but can also be provided with a different function from
the alarm function. Further, it is also possible to provide a
plurality of additional functions.
In this case, the first index 21 is configured so as to be able to
indicate the types of these functions, and in the case in which the
first index 21 indicates the type of the additional function, the
function hands 61, 62 indicate the information related to the
function of the type thus indicated.
As the different function from the alarm function, there can be
cited the chronograph function for measuring the time, the timer
function for measuring the time from the time set in advance in a
countdown manner, and so on. In this case, the function hands 61,
62 indicate, for example, the measured time.
Further, although in the fourth and fifth embodiments described
above, the two function hands 61, 62 are provided, the invention is
not limited to this configuration. For example, in the case in
which only the minute of the measured time of the timer function is
indicated by the function hand, the number of the function hands
can be one.
Although in the sixth through ninth embodiments described above,
the second index 13 indicates the value of the day information in
the case in which the first index 21 indicates the day of the week
or the type of the function, the invention is not limited to this
configuration. Specifically, in this case, it is also possible for
the second index 13 to indicate the value of the month information,
the value of the elapsed-year information, or other information
instead of the value of the day information. It should be noted
that in this case, it is sufficient to display a symbol
representing the day in the periphery of, for example, the first
small window B20, and to arrange that in the case in which the
first index 21 indicates the symbol, the second index 13 indicates
the value of the day information.
Although in the sixth through ninth embodiments described above, in
the case in which the first index 21 indicates the day of the week,
the character "M" representing the month, or the character "L"
representing the elapsed years, the function hands 61, 62 indicate
the hour and the minute of the current time, the invention is not
limited to this configuration. It is also possible to indicate the
information related to the function such as the alarm time or the
measured time.
Although in the sixth and ninth embodiments described above, the
analog electronic watch is provided with the alarm function and the
chronograph function, the invention is not limited to this
configuration. Specifically, it is also possible to provide only
either one of the alarm function and the chronograph function.
Further, although in the seventh and eighth embodiments described
above, the analog electronic watch is provided with the alarm
function, the invention is not limited to this configuration.
Specifically, it is not necessary to provide the alarm
function.
Further, in the analog electronic watch according to any one of the
sixth through ninth embodiments described above, it is also
possible to provide other functions instead of or in addition to
the alarm function, the chronograph function, the timer function,
and the dual time display function. In this case, the first index
21 is configured so as to be able to indicate the types of these
functions, and in the case in which the first index 21 indicates
the type of the function, the function hands 61, 62 indicate the
information related to the function of the type thus indicated.
Further, although in the sixth through ninth embodiments described
above, the two function hands 61, 62 are provided, the invention is
not limited to this configuration. For example, the number of the
function hands can also be one or three.
